ABSTRACT:
An antibandit shutter includes a closed frame made up of a lower housing, an upper head and two side mullions defining a space which can be opened or closed. The opening or closing is effected by a plurality of elongate slats adapted to move from a retracted position within the confines of the lower housing to an expanded and raised position substantially closing off the space. The slats are guided along the mullions of the frame by a raising mechanism formed from a plurality of crossed first and second lever arms in the form of a lazy tongs mechanism, where the first lever arms are formed by the edges of the slats and the second lever arms are formed from slave levers.
